Answer:
2500 people PER square mile
Step-by-step explanation:
THe population density is the population per unit area.
Here,
Given:
Population = 400,000
Total Area = 160 sq. miles
To get population density, we would need the population PER UNIT AREA, per miles.
We can get that by dividing the total population by total area:
400,000/160 = <u>2500 people PER square mile</u>
This is the population density.
For this case we must simplify the following expression:
By definition of the law of multiplication signs we have to:
So, rewriting the expression we have:
Thus, the answer in decimal form is 1.15.

Answer:
y = 3
Step-by-step explanation:
The answer would be A. <span>The registration fee is $5.50, and the cost per download is $0.95.</span>
Solution
Let x = registration fee
y = cost/downloads
Jack
15y + x = 19.75 ; x = 19.75 - 15y
Jim
40y + x = 43.50
Thus,
40y + x = 43.50
40y + <span>19.75 - 15y = 43.50
</span>25y = 23.75
y= 0.95
for x,
<span>x = 19.75 - 15y</span>
x = 19.75 - 15( 0.95)
x= 19.75 -14.25
x = 5.5
